IMPROVEMENT-IN ROOKIE-SIGNAL DliVIlOB.

fiigefitinbuls nitmt is in first Zfstisrs sum int mating pm TO ALL wnom 1r msv'concusm Be. it known that I, 34003 .7 Ds irvmnpr', of .Greenviile, county of Hudson, State ot' New Jersey, have invented ccrtsin new and useful Improvemen in Telegraphic Night-Signals; and I do hereby declare the fol-. loving to bee full, clear, and exact description thereof, reference being bad to 'the accompanying drawings, which form part of this specification, and in whicht Figure 1 represents an elevation of sn apperatus illustrating my invention as applied to signalling by hand.

Figure 2 is a perspective view of the some, with the parts detached.

Figures 3 and are respectively esectioual and a. perspective view of an empty cup adapted for the reception of apyrotechnic compound to produce light of any desired color.

-Figurcs 5 and 63ers sectional andperspective views of the same charged.

Figure 'i represents a side elevation of a rocket.

Figure 8 represents an axial section thereof fully charged. V

Figure 9 is a perspective view of the some, with the parts separated in readiness forcharg'ing.

Similar letters of reference in the several figures refer to corresponding 'psrts.

My invention consists- First, in the'construction and use 05 metallic cups adapted for the reception and burning of pyrotechnic compounds,- and formed with spiral grooves for attaching them to a stat? or to a suspending-chain, or other object. 7 I

Second, in the combination ofa number of such metallic cups, constructed and arranged to be interchangeable at will foreithibit'ing various-colored lights in any consecutive order desiredf Third, in a. peculiar construction of stafi or handle for holding and exhibiting the signal-cups.

Fourth, in a peculisr'construction of rocket-csse, adapted to be readily opened had closed, for the recep tlon of the pyrotechnic cups. 1

Fifth, inasuspendedscrew-cup for the rcce'ption of a singleor combined signal, as hereinafter described.

Sixth, in the employment or use of a; parachute introduced in a compressed state within. the head of a.

bcket, in such a. way as to avoid danger of displacement or entanglement during storage or transportation, and lessen resistance in flight, and adapt-it to he' brought into elfectivc action instantaneously on the exploding of the rocket. I 4 4 The following description will enable any one skilled intvthe art to which my invention upprtnin's to construct and use it. i

A)? A represent metallic cups formedon the periphery, \vithe continuous spiral groove, :1, and tapering towards the bottom or closed end, in the centre of which is an aperture, a.

B represents pyrotechnic composition placed within the cups and'adapted to burn with light of any desired colors. The color of the light which the charge of any cup will producemay beindicate'd by that of the paper, mad, or cup by which it is confined within the cup, or by colored papers? paint applied to the'outside ofthe cup;

6 represents the fuse, by means'of which the charge of the fir'sfcup is ignited,'either by hand or by the explosive charge of the rocket, and the charge of each succeeding 'cup froin the preceding one through the aperture a.

By the tapering form of the cups and thespiral grooves on their. peripheries, they is adopted to be readily screwed together, in the manner represented in fig. 1, in any consecutive order, and the last one may be screwed into a spiral-wire socket, C, mounted in a stall or handle, 1).

The fuse b of the first cup being ignited, the contents of this cup will burn until it is consumed, and then communicatefire through the'apcrturc a to the fuse of the second, and so on till all have burned out.

The cups may be made of fusible metal, so that each will bezdropped as soon as done with, and thus ofl'er no impediment to the burning of the contents of the rest.

charge.

In figs'. 7, 8,'snd 9, E represents the body of a rocket, F, the customary stich-aock t, and G the elevoting- The head H of the rocket is made separately, and attached to the body bya bayonet-joint, I, or other suitable faetening; jrhich will nerve to eeouro it whilo in use, but permit its ready detachment arid ottlehmont when desired, for the purpose of introducing the connected aignal-cupa A A. A in. any deaired nnmher, the last of which is secured to ecrew aocket 0', attached by a chain, J, to the cords K ofa parachute, L, which it cougar-cased into the head 0? the rocket, as shown in fig. 8.

M represents aialov able onp'cloaing'tho top of the rocket, and N a diaphragm separating the parachutechau'iber fromthoso in vhieh the'oxplorive and pyrotechnic compounds are ignited.

The operation of my invention, ne applied to rockets, may he described all follow.

A: the rocket appronohee the upward limit of its flight, the explosive charge ignite: the Fuse 6 of "Mind cup A, and either shatter: the head entirely, or blow: the signal-cup! A A A, diaphragm Nflnd parachute L, and their connectionnlbodily out through the upper-end of the rocket, carrying ol' the an H. The night of theattaehed signaLcups A A A, and the resistance of the ntloqihere, cause the parachute to expand instantaneously, and to suspend the cups for a euflieient length of tile for the combustion of their eontonta,

Having thus described my invention, what I claim as new therein, 'and desire to secure by Letters Patent, il

1. A metallic signal-cup, A, grooved spirally for'attechuient to n ska! or suspension-cup, aa and for the purpose set forth. I I

2. The combination o two or more cups, A A A, tapered and grooved, as herein dflhibea, to like them relatively interchangeable, for the purposes specified; e l 3. The spiral socket 6', constructed and adapted to receive and hold the cnpa A, an int! for the per-pole. described.
